New H1B petition after the old H1B has expired

[st003]

I have a H1B visa which was first issued to me on Oct 2005. I returned back to India in Oct 2009 and I again came back to US in March 2011 after a gap of more than 1 year. My petition got extended till May 2013 which means I will be completing 6 years on this H1B visa.

My question is will I be eligible for a new H1B visa starting April 2013 since I already have a break of more than 1 year from 2009 to 2011?

Or I will have to spend another year away from US before I become eligible for a new H1B visa?

Thanks,
